arrow design change

[Parikshit-Hooda]

The arrow/triangle symbol that are deployed currently can use a bit more improvement on the alignment and streamlining front.
For example, The arrows for incoming and outgoing are not distinguishable. I think a colored tip to show the direction of HTTP request can improve the experience of user. If a request to Facebook tab is going outside, the 'arrow/triangle' symbol can put a red color on the tip. Similarly, a different color for the incoming request. I started using this today, and I think this would be a cool enhancement to distinguish and majorly reduce the time spent in examining the requests by classifying as incoming or outgoing.

The arrow/triangle symbol can also be changed as there are better alternatives available.

This is my humble opinion, the criticism is welcome obviously.
